apache扩展模块安装
因为需求，所以我要安装一个扩展模块，该扩展模块名为mod_headers，那应该怎样去添加扩展模块呢？首先，添加扩展模块要用到的工具是：/usr/local/apache2/bin/apxs
也就是Apache的安装路径下的目录中
首先，去你下载的源码包目录中。就是你刚开始安装Apache的时候（./configure的时候），该源码包看你放在哪，一般是在/usr/local/src/目录下的
#cd/usr/local/usr/
之后在当前目录下查找mod_headers.c文件放在哪？
#find/usr/local/src/httpd-2.2.31 -name "*.c" | grep'mod_headers.c'
#cdmodules
#cdmetadata
在该目录下，执行安装命令：
#/usr/local/apache2/bin/apxs -i-a -c mod_headers.c
# /usr/local/apache2/bin/apxs-i -a -cmod_headers.c
/usr/local/apache2/build/libtool --silent --mode=compile gcc -prefer-pic -DLINUX -D_REENTRANT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -g -O2 -pthread -I/usr/local/apache2/include-I/usr/local/apache2/include -I/usr/local/apache2/include -c -o mod_headers.lo mod_headers.c && touch mod_headers.slo
/usr/local/apache2/build/libtool --silent --mode=link gcc -o mod_headers.la-rpath /usr/local/apache2/modules -module -avoid-version mod_headers.lo
/usr/local/apache2/build/instdso.sh SH_LIBTOOL='/usr/local/apache2/build/libtool' mod_headers.la /usr/local/apache2/modules
/usr/local/apache2/build/libtool --mode=install cp mod_headers.la /usr/local/apache2/modules/
cp .libs/mod_headers.so /usr/local/apache2/modules/mod_headers.so
cp .libs/mod_headers.lai /usr/local/apache2/modules/mod_headers.la
cp .libs/mod_headers.a /usr/local/apache2/modules/mod_headers.a
chmod 644 /usr/local/apache2/modules/mod_headers.a
ranlib /usr/local/apache2/modules/mod_headers.a
PATH="$PATH:/sbin" ldconfig -n /usr/local/apache2/modules
----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/apache2/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
chmod 755 /usr/local/apache2/modules/mod_headers.so
-c ： 编译
-i： 安装
-a ： 在配置文件中自动添加IfModule信息。（配置文件：/usr/local/apache2/conf/httpd.conf）
#cat /usr/local/apache2/conf/httpd.conf | grep 'LoadModule'
查看有没有成功安装：/usr/local/apache2/bin/apachectl -M
